Olaplex
Nº.4 Bond Maintenance Shampoo
Every wash is either building bonds or breaking them. Olaplex No.4 does both — cleanses while the patented bis-aminopropyl diglycol dimaleate reconnects the broken disulfide bonds that make hair fragile. For color-treated, bleached, relaxed, or heat-damaged hair. Non-negotiable if you're doing any chemical services.
